SWING.

SPECIFICATION forming part of Letters Patent No. 320,432, dated June 16,1885'.

Application filed November 21, 1884.

To all whom it may concern:

Be it known that I, WILLIAM W. ELLIOTT, of Galveston, in the county ofGalveston and State of Texas, have invented certain new and usefulImprovements in Swings; and I do hereby declare the following to be afull,

. clear, and exact description of the invention,

such as will enable others skilled in the art to which. it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in swings; and it consists,first, in the combina tion, of a single upright or hanger, to the lowerend of which the swing is secured,a screw-hook, by means of which thehanger is suspended, and suitable castings which catch upon oppositesides of the upper end of the upright for the purpose of steadying theupright in its place 5 second, in the combination of a single upright orhanger with a slotted lever which is provided with a friction-roller tobear against one edge of the hanger, and with a second friction-rollerat its lower end for the operatingcord to pass over, the lever beingmade to increase in thickness from its lower end upward, all of whichwill be more fully described hereinafter. I

The object of my invention is to provide a swing which consists of asingle upright or hanger and a mechanism by means of which the personsitting in the swing has but to pull upon the cord and cause the swingto freely move back and forth.

Figure l is a side elevation of a swing embodying my invention. Fig. 2is a front view of the same.

A represents a suitable support or frame in which the swing is to besuspended, instead of a frame which is made especially for the purpose.The swing may be suspended from the ceiling or any other suitablesupport. The single hanger or standard B is supported at its upper endby means of a screw-hook, D, which has its lower end made L-shaped, soas to pass through the upper end of the hanger, as shown.

In order not only to hold the hanger in place, but also to guide andsteady the movement of the hanger, a suitable casting, D, is placed uponeach side of the upper end of the (No model.)

hanger, as shown. These castings serve to prevent any lateral play orvibration of the hanger as it swings back and forth. At a suitabledistance below the upper end of the hanger a suitable enlargement, E, isformed upon its side, for the purpose of enabling the operating lever togive the hanger a greater throw or movement.

Secured to the front edge of the hanger is a suitable metallic plate, G,which passes up over the top of the hanger and down upon its oppositeside, for the purpose of strengthening the hanger, and for thefriction-roller of the operating-lever to bear against without wearingout or injuring the hanger itself.

Through the hanger, at any suitable point, is madea suitable slot, andin this slot is pivoted a friction-roller, H, under which theoperating-cord passes.

' To the lower end of the standard is secured a swing, which may be ofany suitable con struction.

The operating-lever K is slotted for the greater portion of its length,and is pivoted or suspended at its upper end, in any desired relation tothe upper end of the hanger, in a suitable casting or support, I. Jonrnaled in the slot in this lever is a friction-roller, J, which bearsagainst the metallic plate on the front edge of the hanger, as shown. J

In the lower end of the operatinglever is journaled a secondfriction-roller, over which the operating-cord passes. Thisoperatingcord is fastened to the support A, passes down under thefriction-roller that is journaled in the hanger, up over thefriction-roller that is journaled into the lower end of theoperatinglever, and then down to the person in the swing. When a pull isexerted upon the lower end of this rope, the lower end of the lever isdrawn downward, and in doing so the hanger is forced backward. As soonas the tension upon the cord is released the gravity of the swing causesit to swing forward again, when a second pull upon the lever forces itbackward again.

The width of the operating-lever is made to increase from its lower toits upper end, so that the hanger can pass freely through it, as shown.The increase in width upon the front edge of the hanger enables aquicker and a greater amount of movement to be imparted to the hangerthan can be done where the hanger is of a uniform width.

I am aware that the upper ends of the hangers of a swing have beenpivoted between the ears of castings; but these ears do not hold theends of the hangersnpon the pivot upon which they are placed, and this Idisclaim.

Having thus described my invention, I claim- 1. The combination of asuitable support, a suspension-hook, a single hanger, and suitablecastings, which are applied to opposite sides of the upper end of thehanger for the purpose of guiding its movement, substantially as shown.
